VIOFO Coaxial Cable for A329 Series – Rear, Interior & Telephoto

The Coaxial Lead the A329 Platform Runs On. Rear, interior and telephoto, up to 20 m

The A329 generation moved to coaxial connections, which is why none of the Type-C leads from the A229 range will plug into it. This is the correct cable for that platform, and the rear version goes all the way to 20 m, which is the longest run we stock for anything. If you are wiring a bus, a truck or a caravan, this is the one.

Who This Isn't For: VIOFO lists this for the A329, A329S and A329T series, plus the A229 Duo, and states it is not compatible with the A229 Plus or A229 Pro — those take the Type-C A229 rear cable instead. It is also not waterproof, so if you are running an exterior camera you need the waterproof version. VIOFO's own listing is inconsistent on the A229 side, so message us with your exact model if you are unsure.

DCG Score & Highlights

What We Love

• Rear runs up to 20 m, the longest single lead we stock
• One cable family covers rear, interior and telephoto connections
• Short 0.15 m and 0.3 m options for interior and telephoto cameras mounted beside the main unit
• Coaxial construction, matched to the A329 platform's connection
• Genuine part, so no dropouts from a marginal third-party lead

What Could Be Better

• Not waterproof. Exterior cameras need the waterproof cable instead.
• Not for the A229 Plus or A229 Pro, which use Type-C.
• VIOFO's own product page gives conflicting compatibility information, so confirm your model before ordering.

Why the A329 Uses Coaxial

Coaxial carries a higher-bandwidth video signal further without degrading, which is what allows a 20 m rear run to stay stable when a USB lead of that length would not. It is the reason the A329 platform can support genuinely long installs in trucks and buses, and also the reason its cables are not interchangeable with the older Type-C generation.

Top Benefits

• Genuinely long runs: Rear lengths to 20 m for buses, trucks and caravans.
• Covers three channels: Rear, interior and telephoto in one cable family.
• Short options too: 0.15 m and 0.3 m for cameras beside the main unit.
• Stable signal: Coaxial holds up over distance where USB would not.
